Imagine I could only choose 5 sci fi books for a brand new sci fi reader – what would they be?
- Dune by Frank Herbert
- The Martian by Andy Weir
- The Hitchhiker's Guide to the Galaxy by Douglas Adams
- The Moon is a Harsh Mistress by Robert A. Heinlein
- Doomsday Book by Connie Willis
That should be a nice cross section, though I completely ignored cyberpunk, near future apocalyptic (unless you include Hitchhiker's Guide!), alternate history, and a few others!
